Detailed description of preferred embodiment

Fig. 1 and 2 shows an equipment 10, it be arranged to make on the carrier 16 basically forward and flap 12 and 14 backwards reorientate, this carrier is transmitted along a feeding path 18 of the equipment of a standard, is used in the bottled input tray.This equipment 10 comprises a continuous belt 20, and in this embodiment, this belt has installing three lugs 22 thereon.This belt is provided with round a driving rolls 24 and a return idler 26.Under the control of a control setup 30 (Fig. 6), a CD-ROM drive motor 28 (Fig. 6) provides the controlled motion of the driving rolls 24 of power to make driving rolls 24 rotation, makes 20 motions of continuous belt, this so that make return idler 26 rotations.Best, CD-ROM drive motor 28 is servomotors.Continuous belt 20 can be made such as rubber by ferrodo, and can make its motion owing to the friction between roller 24 and this continuous belt 20.In addition, CD-ROM drive motor can have a toothed section, and as illustrated in Figure 3, in the process of using, each tooth is accommodated in the recess of cooperating with it 27 of continuous belt 20, so that make belt 20 motions.

The feeding path 18 of the position vicinity that makes

roller

24 and 26 in bottled year equipment makes the motion of belt 20 will make lug 22 enter this feeding path 18 periodically.

Equipment 10 can make independent lug 22 periodically be arranged in feeding path 18, in the front of carton 16, each carton 16 is contacted with lug 22, and by such flap forward 12 on the carton 16 is reorientated.

Make continuous belt 20 be positioned at certain height, make when using, lug 22 will contact with 14 with back flap 12 with the preceding of carton 16, thereby flap is moved.Further explain this point below with reference to Figure 4 and 5.

Equipment 10 can also periodically improve the speed of lug, thereby independent lug 22 is contacted with the flap backwards 14 of carton 16, like this, flap 14 is backwards reorientated.In the present embodiment, adopted the variable continuous belt 20 of mono-speed.Yet, also can use many belts.In addition, can adopt the mono-roller, it has attaching one or more lugs 22 thereon, and does not use continuous belt.

As shown in Fig. 1 and 2, the form of lug is preferably T shape part, is provided with the interval that equates round continuous belt 20.The pedestal 32 of each lug 22 is connected on the continuous belt 20, make that with respect to feeding path 18, the first arm 34 of T shape part will stretch out in the front of pedestal 32 when using, and second arm 36 of T shape part will stretch out in the back of pedestal 32.The arm forward of T shape part and the end of arm backwards are provided with elastomeric part 38 and 40, and they are for example made by rubber, make that the possibility of in use bottle in the carton 16 being damaged is minimum.

Comprise a control setup 30 at the device shown in Fig. 6 10, it is arranged to control the speed of continuous belt 20 in use.This control setup can be the treater of a special use, perhaps can be the control setup of the packaging machine that therewith uses of device 10, and this control setup is suitable for control convenience 10.In addition, preferably a kind of known programmable servo control unit of control setup.

Control setup 30 is arranged to sensor 42 to detect the speed of continuous belt 20 by a sensor 42 reception information; This sensor can directly detect the speed of belt, perhaps, can detect the speed of driving rolls 24.In addition, equipment 10 comprises that form is the device of sensor 44, is used for receiving the information about the speed of carton on feeding path 18, and this information is passed to control setup 38.In addition, manual input media 46 can be arranged, can be input into control setup 30 to the speed of carton 18 on the feeding path by this device.

As illustrated in Figure 2, equipment 10 is installed on the pair of guide rails 48, they stretch perpendicular to feeding path 18, therefore make device 10 can enter a run location, in this position, a lug 22 stretches out when using, enter feeding path 18, and the position forwards the position of a back to thus, in this position, that lug 22 will not stretch and feed material path 18.Like this, the packaging machines that therewith use when device 10 are loading when not needing to make the carton that flap reorientates, and equipment 10 is withdrawed from.

Before the method for operation of discussion equipment 10, it may be useful describing the carton 16 that equipment 10 can therewith use in detail in the mode of example.

Fig. 4 shows a such carton 16, and it has an antetheca 50 and a rear wall 52, and each wall is divided into the

flap

12 and 14 on a bottom 54 and a

top.Flap

12 and 14 and the bottom 54 of antetheca and rear wall 50 and 52 all opened in 56 minutes by crease (or folding line), these folding lines make flap to be pivoted about the bottom 54 of each wall.On each side 60 of the carton between the top surface 62 of the sidewall bonded assembly position of folding line 56 and carton and carton, be provided with second crease (folding line) 58.This folding line is set makes that sidewall can be a little to excurvation, allow that

flap

12 and 14 can reorientate facing to the necks 62 of the bottle 64 in the carton 16, as by dotted line 63 and 65 shown.For such carton 16, it may be suitable that lug 22 roughly contacts with flap in the centre.Yet, if flap be not fully towards preceding or towards after, and be the band angle to a certain extent, so, it may be suitable that lug 22 contacts with certain other parts of flap.In addition, can use two equipment, as illustrated in Figure 5, under the sort of situation, will be arranged to each lug 22 not contact with flap, but contact with flap in a desired location near the side 60 of carton 16 at the center.

When using, make equipment 10 enter a position, in this position, lug 22 will stretch out, and enter feeding path 18, as illustrated in Figure 1.When starting this equipment, make the device 46 (Fig. 6) of input by hand be input into control setup 30 to the speed of the continuous state of the conveyer that transports carton 16.Like this, when equipment 10 entered the use location, it is above or contact with the

suitable flap

12 or 14 of carton 16 with the specific percentum of the next one that lug 22 will be provided in the speed in feeding path, as below will at length discussing.

In the process of initial start, be used for along the feeding path 18 advancing the conveyer of cartons 16 and the running velocity that continuous belt 20 all little by little is increased to speed a standard.To all be controlled to these two equipment and make that this process will be gradually, can not cause damage for carton 16 or their content.

If we at first discuss one embodiment of the present of invention, in this embodiment, two equipment 10 have been used, and the effect of consideration mono-lug 22, there is dual mode to consider the process of reorientating, this depends on that you consider that lug is at first to contact with forward flap, still at first contacts with backwards flap.For example, if the position of lug 22 in the feeding path in the front of a carton 16, the speed of the carton 16 of velocity ratio on the feeding path is low, so, carton 16 will contact with lug 22, preceding flap 12 will be relocated.Then, control setup 30 will improve the speed of motor 28, and this will make lug 22 gather way, and turn around around the track of continuous belt 20, and lug 22 is contacted with the back flap 14 of same carton.

Yet, if you consider that lug 22 initially contacts with the back flap of first carton, and, subsequently the speed of lug 22 is reduced to lower than the speed of the carton in feeding path 18, so, lug 22 just will contact with the preceding flap 12 of the 18 next cartons that promote along the feeding path.These two processes are identical basically, and the position in circulation is only depended in difference, and we begin to analyze at this position.If we consider to have the embodiment of a plurality of lugs, slow down at first lug 22, after making that the preceding flap 12 of a carton 16 is reorientated, improve the speed of lug 22, first lug is shifted out by the path of carton, and second lug is contacted with the flap backwards of this carton, as illustrating in order among Fig. 5.

Fig. 5 show equipment embodiment and the carton that just on the feeding path, is transmitting forward and five steps of reorientating of flap backwards.In step 1, lug is moved into the feeding path.Subsequently, lug is quickened, it is contacted with backwards flap, and this flap is reorientated, as step 2 is shown with respect to the speed in feeding path.Then, when carton leaves equipment, with respect to the speed in feeding path lug is slowed down, thereby lug is contacted with the flap forward of next carton, and these flaps are reorientated, as step 3 is shown.In step 4 and 5, lug is slowed down, remove by the feeding path.Subsequently, the motion of the lug of back enters the feeding path in the carton back, and, the program above repeating.

In the time can being located at a carton 16 between two lugs 22, it be actvies that three lugs 22 are arranged on continuous belt 20; One in the front of carton, and one in the back of carton, and can not disturb in feeding path 18 16, the three positions of lug 22 on this continuous belt 20 of remaining carton for to leave the position in feeding path 18 constantly at this.When quicken one of the foremost in making these lugs 22, the path of shifting out lug 22 at its fwd carton 16 along feeding path 18.At any one constantly, can use no more than two lugs in feeding path 18, because of at that constantly, the 3rd lug 22 may need a carton 16 is remained on the front of middle lug 22, and rearmost lug 22 is accelerated, and contacts with the back flap 14 of rearmost carton 16.Yet this may mean second lug 22 and repeatedly contact with second carton 16, and this may cause damage.

When top lug 22 is slowed down, when a carton 16 is contacted with this lug 22, the speed of the carton 16 that the velocity ratio of continuous belt 20 is advanced along feeding path 18 low 1 to 30%.Similarly, when this lug 22 is quickened, make that the speed of continuous belt 20 is higher by 1 to 30% than the speed of the carton in the feeding path 18 16 when contacting with rearmost flap 14.Best, under first kind of situation, make the speed low 20% of the kinematic velocity of continuous belt 20 than carton 16, under second kind of situation, higher by 20% than the speed of the carton in the feeding path 16, because this will provide enough application forces, each flap is reorientated, and do not damage carton 16.

During the speed of carton is bottled in the other part that adapts to the bottling process in changing the feeding path speed, also to change the speed of continuous belt 20, thereby the speed of continuous belt 20 be remained in the scope of these percentums.Yet, have some situation, in these cases, need fast speeds or slower speed, for example, if when using a kind of thick especially production carton, just may need to do bigger change,, the flap above it be reorientated to cause enough big application force.In addition, if use an equipment or use two equipment, can change speed.

Fig. 7 has schematically shown an equipment 70 that is used for bottled input tray 16, shows according to the present invention and is used for the position of equipment 70 of equipment 10 that flap is reorientated.This equipment 70 comprises a carton bank and feed mechanism (square frame 72), take out carton 16 by the there, and deliver to a mechanism (square frame 74), perhaps pass through round bottle coiling carton, perhaps by bottle is put in the carton, this mechanism makes bottle combine with carton, and this depends on the type of employed carton.Bottle is sent in this mechanism by a storage area (square frame 76) with predetermined speed and predetermined setting.In case carton and bottle are combined, and suitable blocking device pins carton a position in a kind of known mode, common pedestal (square frame 78) at carton.Then, the

flap

12 and 14 of carton is reorientated (square frame 80), and carton is delivered to a storage area (square frame 82), can be contained in them in the crate, be used for transporting by this zone according to the present invention.The process that can make in square frame 78 and 80 expression in according to some equipment of the present invention out of order.

Although here the preferred embodiment of Miao Shuing is to be used for bottled input tray,, will recognize that, the invention is not restricted to be used for the carton of bottle.The present invention can be with the machine of jar, cardboard " brick " and other bottle packing input tray is used.

Also have, although here the preferred embodiment of Miao Shuing is that conduct is used for a part of advancing the machine of cargo-carring vertically socket type carton bottled,, the present invention does not limit such carton.The personage that present technique is familiar with will recognize that the present invention can use with the cargo-carring carton of convoluted carton or end, and can be used for multiple carton flap is reorientated, and these flaps are used for fixing or other purpose.

Can comprise a plurality of remodeling, and not depart from by the determined scope of the present invention of appending claims.
